Roses riem, citizens of the l United States, residents of Clcveland,county lof Cuyahoga, and State of Ohio, respecl tively, have invented a new and .useful Imt irovement in Floor-Plates, of which the folliowing is a specification, the principle of i i l best inode in which we have contemplated it from other inventions.

plates for coverinfr apertures .through which pass pipes or theike, the object ot said invention being to provide such a tloor plate y which may be secured in place after the pipe has been placed in position, and which will j present a smooth and finished exterior appearance.

1 The said invention consists of means hereinafter fully described and particularly pointed out in the claims.

z The annexed drawing and the following i deseri )tion set forth in detail certain iiieiins Q embodying our invention, the disclosed l means, however, constituting but on'e lof various mechanical forms in whielithe principle of our invention nia v he applied. In said annexed drawings: ligure l is a l tliroii h a floor, and showing one of our ini- Eprove plates in position thereon.

in their noi-nial or closed position. l"ig. 3 is n bottoni plan of said tlooil phite showing the parts in a detached and partiell)I open position. Fig. l is' a bottoni plan ol n lloor plato showing the parts in tlieii` open positioii.

(hir iii\eii|ion nilliisti'nteil consists ol tuo semi-annular members and li preferably strut-lv' up of .sheet metal so as to foi-in n marginal llaiige i on the plate. 'l`he interior circular owning is inade ot a diameter .such as wi l permit the plate to he titled closely around the particular size oi' pipe to which it is to he applied. 'lo the under side of llial portion oteaeli ofthe iiiemhei'sadjacent to the contiguous edges (1,' and b' of the members A and l respectively, is secured a hinge C, the hitter being placed intermediately of the two inner and outer edges a* and of the plate. This hinge hasl two )ivotal axes a." und b whichintcrseet the pllatc perpendienla'rly and which are located in two diflerent parallel planes perpendicular to the edges a and b when in their normal or contiguous position. This construction gives the hinge two axes of oscillation` so that thel two parts may be moved into the the invention being herein explained and the` applying that principle, so as to distinguish Oni` invention relates to lloor or ceilingj i perspective of a section of a pipe passing Fig. 2i is a bottom plan of a tloor plate embodying our invention, the parts thereof heilig shown,

position shown in Fig. 3, the hinge oscillating about the axes a. and b. By now turning the member A about the axisJr1 and simultaneously turning it about the axis a, the two parts may be separated to assume the position shown in Fi". 4, in which po- ;sition it may be placed about the pipe and closed thereon. The outer swinging end of the member A is provided with a fixed fastening member o which rojccts beyond thc outer end of this member, such projecting portion being formed with an aperture n". The free or swinging end of the member B is formed with a struck-up projection b, which is adapted to engage the aperture a", there being snllicient spring in the device to permit such engagement, or after such enagenient. to permit a disconnection of ineinier a* from the projection b.

Tn order to hold the plate in place lsnugly around the pipe, a yielding spring I) is se-` cured to one nt' the members and projects into the interior opening a portion b" of ,the metal being struck up so as to forin a @projection to which the spring T) niay be, secured. One of the members is provided with a struck-up projection a on its under side. which may be driven into the lloor or ceiling and so prevent turning ot' the plate on thc pipe.

llaving fully described our invention. what we claim and desire to secure by Let- ,ters Patent is: 1. A floor plate comprising the combina- .,tion with tivo surrounding members having two normally contiguous extremities when in theii closed osition; of a hinge having l an iixis on eiiei of Isaid members and adjai eent to said extremities; said axes being pei'- l pendienlar to the planeet' movi-ment ol' said members, und loented in two ditlerent planesl perpendicular to the .line of contigiiity of said extremities.

L. lloor plate eouiprising the eoiiiliiiiution of two tint semi-annular iin-inhers liiiving two normally contiguous extremities; a hinge joining that part of said members ailjacent to said extremities. and having :in axis ot oscillation on each ol` same perpeng dicnhir to the. pliiiie of movement thereof; said axes furthermore heiiig located in two dtlerent. pliiiies perpendicular to the line ot i contigiiity of said extremities.
